  • Remove files from Bazaar

    - by Kristopher Ives
    I'm using Bazaar (bzr) to keep source code for a website updated, but we've ran into a problem when we remove files from version control. The files we are removing are ones we never intended to version to begin with. When this happens we use bzr rm --keep to remove the file from version control, but keep the file in the file system. Doing a bzr push or bzr pull results in the removed file(s) being removed on the other branches (other sites that use our code) We need a way to make sure that a bzr push or bzr pull doesn't actually remove those from the working copy. Anyone have any ideas?

  • How to make new file permission inherit from the parent directory?

    - by Wai Yip Tung
    I have a directory called data. Then I am running a script under the user id 'robot'. robot writes to the data directory and update files inside. The idea is data is open for both me and robot to update. So I setup the permission and owner group like this drwxrwxr-x 2 me robot-grp 4096 Jun 11 20:50 data where both me and robot belongs to the 'robot-grp'. I change the permission and the owner group recursively like the parent directory. I regularly upload new files into the data directory using rsync. Unfortunately, new files uploaded does not inherit the parent directory's permission as I hope. Instead it looks like this -rw-r--r-- 1 me users 6 Jun 11 20:50 new-file.txt When robot tries to update new-file.txt, it fails due to lack of file permission. I'm not sure if setting umask helps. In anycase the new files does not really follow it. $ umask -S u=rwx,g=rx,o=rx I'm often confounded by Unix file permission. Do I even have a right plan? I'm using Debian lenny.

    Hi, When I c/c++ application fails with the following CRITICAL, can you please tell me how can I find out where is the code causing the error? I have tried to run it in Debugger, trying to do a 'bt when the program fails. But it does not show where is the code causing the CRITICAL: (process:3155): GLib-GObject-CRITICAL **: /build/buildd/glib2.0-2.22.3/gobject/gtype.c:2458: initialization assertion failed, use IA__g_type_init() prior to this function (process:3155): GLib-CRITICAL **: g_once_init_leave: assertion `initialization_value != 0' failed (process:3155): GLib-GObject-CRITICAL **: /build/buildd/glib2.0-2.22.3/gobject/gtype.c:2458: initialization assertion failed, use IA__g_type_init() prior to this function (process:3155): GLib-GObject-CRITICAL **: /build/buildd/glib2.0-2.22.3/gobject/gtype.c:2458: initialization assertion failed, use IA__g_type_init() prior to this function (process:3155): GLib-GObject-CRITICAL **: /build/buildd/glib2.0-2.22.3/gobject/gtype.c:2458: initialization assertion failed, use IA__g_type_init() prior to this function (process:3155): GLib-GObject-CRITICAL **: g_type_add_interface_static: assertion `G_TYPE_IS_INSTANTIATABLE (instance_type)' failed (process:3155): GLib-GObject-CRITICAL **: /build/buildd/glib2.0-2.22.3/gobject/gtype.c:2458: initialization assertion failed, use IA__g_type_init() prior to this function Thank you.

  • Load testing a quicktime streaming server from ubuntu machine

    - by ebeland
    I have software that can launch and control multiple firefox browsers on Ubuntu EC2 images. I need to run a small load test against a QuickTime Streaming server. The stream starts automatically when loaded in a browser that has the QuickTime plugin, so I don't need to automate the stream once it starts. Alternately, I can also make these machines run arbitrary ruby code or executables. How can I get these ubuntu machines to pull in the stream? Also, how can I capture bandwidth usage (maybe a shell script?) on the worker machines?

  • Archlinux auto-start after I shutdown my computer

    - by madper
    every one. I'm in a big trouble. My computer (HP ProBook 4230s) has two OS----Archlinux and Win 7. When I use Archlinux, after halt my computer, it will start up after a while without press power. And there is an other thing. My computer's clock will be wrong. Many times I change it in bios, but it wrong again. If I turn off the computer from Win 7, it will never start up untill pressing power bottom. And the clock will be right. I also used ubuntu\debian\mageia, and both of them are fine with my notebook. Is there some configure is wrong with my ArchLinux?

  • Epoll in EPOLLET mode returning 2 EPOLLIN before reading from the socket

    - by Arkaitz Jimenez
    The epoll manpage says that a fd registered with EPOLLET(edge triggered) shouldn't notify twice EPOLLIN if no read has been done. So after an EPOLLIN you need to empty the buffer before epoll_wait being able to return a new EPOLLIN on new data. However I'm experiencing problems with this approach as I'm seeing duplicated EPOLLIN events for untouched fds. This is the strace output, 0x200 is EPOLLRDHUP that is not defined yet in my glibc headers but defined in the kernel. 30285 epoll_ctl(3, EPOLL_CTL_ADD, 9, {EPOLLIN|EPOLLPRI|EPOLLERR|EPOLLHUP|EPOLLET|0x2000, {u32=9, u64=9}}) = 0 30285 epoll_wait(3, {{EPOLLIN, {u32=9, u64=9}}}, 10, -1) = 1 30285 epoll_wait(3, {{EPOLLIN, {u32=9, u64=9}}}, 10, -1) = 1 30285 epoll_wait(3, <unfinished ...> 30349 epoll_ctl(3, EPOLL_CTL_DEL, 9, NULL) = 0 30306 recv(9, "7u\0\0\10\345\241\312\t\20\f\32\r\10\27\20\2\30\200\10 \31(C0\17\32\r\10\27\20\2\30"..., 20000, 0) = 20000 30349 epoll_ctl(3, EPOLL_CTL_DEL, 9, NULL) = -1 ENOENT (No such file or directory) 30305 recv(9, " \31(C0\17\32\r\10\27\20\2\30\200\10 \31(C0\17\32\r\10\27\20\2\30\200\10 \31("..., 20000, 0) = 10011 So, after adding fd number 9 I do receive 2 consecutive EPOLLIN events before having recving the file descriptor, the syscall trace shows how I do delete the fd before reading but it should only happen once, one per event. So either I am not reading the manpage properly or something is now working here.

  • Where has my parallel port gone? ioperm(888,1,1) returns -1.

    - by marcusw
    I have an old Dell Dimension 8200 running Gentoo which I use solely to control various things using the parallel port. After shutting it down a few weeks ago, I started it up again today and tried to access the parallel port like I usually do. Unfortunately, my code bombed out when it tried to call ioperm(888,1,1) to grab the parallel port which returned an error code of -1. There have been no changes to the system be it hardware or software, no updates, no tweaking, no dropping the case, no over-amping the data pins, nothing. The port and the software have been working fine for months with no changes, and were working fine when I shut it down last. Running my code with root privileges changes nothing. What is breaking this and how can I fix it?

  • svn over HTTP proxy

    - by small_jam
    Hi all. I'm on laptop (Ubuntu) with a network that use HTTP proxy (only http connections allowed). When I use svn up for url like 'http://.....' everything is cool (google chrome repository works perfect), but right now I need to svn up from server with 'svn://....' and I see connection refused. I've set proxy configuration in /etc/subversion/servers but it doesn't help. Anyone have opinion/solution? Thanks. Anton.

  • Using pthread to perform matrix multiplication

    - by shadyabhi
    I have both matrices containing only ones and each array has 500 rows and columns. So, the resulting matrix should be a matrix of all elements having value 500. But, I am getting res_mat[0][0]=5000. Even other elements are also 5000. Why? #include<stdio.h> #include<pthread.h> #include<unistd.h> #include<stdlib.h> #define ROWS 500 #define COLUMNS 500 #define N_THREADS 10 int mat1[ROWS][COLUMNS],mat2[ROWS][COLUMNS],res_mat[ROWS][COLUMNS]; void *mult_thread(void *t) { /*This function calculates 50 ROWS of the matrix*/ int starting_row; starting_row = *((int *)t); starting_row = 50 * starting_row; int i,j,k; for (i = starting_row;i<starting_row+50;i++) for (j=0;j<COLUMNS;j++) for (k=0;k<ROWS;k++) res_mat[i][j] += (mat1[i][k] * mat2[k][j]); return; } void fill_matrix(int mat[ROWS][COLUMNS]) { int i,j; for(i=0;i<ROWS;i++) for(j=0;j<COLUMNS;j++) mat[i][j] = 1; } int main() { int n_threads = 10; //10 threads created bcos we have 500 rows and one thread calculates 50 rows int j=0; pthread_t p[n_threads]; fill_matrix(mat1); fill_matrix(mat2); for (j=0;j<10;j++) pthread_create(&p[j],NULL,mult_thread,&j); for (j=0;j<10;j++) pthread_join(p[j],NULL); printf("%d\n",res_mat[0][0]); return 0; }

  • get a list of function names in a shell script

    - by n-alexander
    I have a Bourne Shell script that has several functions in it, and allows to be called in the following way: my.sh <func_name> <param1> <param2> Inside func_name() will be called with param1 and param2. I want to create a "help" function that would just list all available functions, even without parameters. The question: how do I get a list of all function names in a script from inside the script? I'd like to avoid having to parse it and look for function patterns. Too easy to get wrong. Thanks, Alex

  • How to declare a(n) vector/array of reducer objects in Cilk++?

    - by Jin
    Hi All, I had a problem when I am using Cilk++, an extension to C++ for parallel computing. I found that I can't declare a vector of reducer objects: typedef cilk::reducer_opadd<int> T_reducer; vector<T_reducer> bitmiss_vec; for (int i = 0; i < 24; ++i) { T_reducer r; bitmiss_vec.push_back(r); } However, when I compile the code with Cilk++, it complains at the push_back() line: cilk++ geneAttack.cilk -O1 -g -lcilkutil -o geneAttack

  • Compiling x264 with mp4 support problem

    - by johnas
    I'm trying to compile x264 with mp4 output support. I download the latest version from their git by typing git clone git://git.videolan.org/x264.git When I run ./configure it configures and I'm able to make it. But when i try to configure it with ./configure --enable-mp4-output and then try to make it, it returns a strange error, indicating that there is a compilation error. The error message looks like: ... Lots of similar errors ... output/mp4.c:297: warning: implicit declaration of function ‘gf_isom_add_sample’ output/mp4.c:297: error: ‘mp4_hnd_t’ has no member named ‘p_file’ output/mp4.c:297: error: ‘mp4_hnd_t’ has no member named ‘i_track’ output/mp4.c:297: error: ‘mp4_hnd_t’ has no member named ‘i_descidx’ output/mp4.c:297: error: ‘mp4_hnd_t’ has no member named ‘p_sample’ output/mp4.c:299: error: ‘mp4_hnd_t’ has no member named ‘p_sample’ output/mp4.c:300: error: ‘mp4_hnd_t’ has no member named ‘i_numframe’ I've tried different releases. I've installed gpac, ffmpeg, and tried numerous tips from the net. But still can't get it to work. The reason I want it with mp4 output is because I want to use ffmpeg to create mp4 files encoded with x264. I'm running Ubuntu Server 9.10 32 bits.

  • How to define an alias in fish shell?

    - by armandino
    I would like to define some aliases in fish. Apparently it should be possible to define them in ~/.config/fish/functions but they don't get auto loaded when I restart the shell. Any ideas? p.s. if anyone is using or has used fish in the past I'd be interested to hear your comments as to whether it offers anything that bash does not.

  • How to define GPS module in Android?

    - by Osama Gamal
    I'm porting android to Devkit8000 which is a BeagleBoard clone. I have a GPS module connected on /dev/ttyS0. I could successfully get NMEA output when writing "cat /dev/ttyS0" in the terminal emulator. I want to know how to let android know that there is a GPS module on /dev/ttyS0 and it is outputting NMEA standard? To be able to use the android.location class with it! Is there something to edit in the android's source? adding driver for example, writing a code with android-ndk or what?
